On April 27, 1991, Patrolman Raymond Paul Rexer, 37, a 14-year veteran of the Bay City Police Department, and his partner Patrolman Terry James Jablonski were shot and killed while responding to a family disturbance in Bay City, Michigan. The officers encountered brothers John and Jeffrey Knapp and were ambushed with gunfire from a .22-caliber rifle.

Jeffrey Knapp was taken into custody at the scene. John Knapp initially fled but later surrendered after asking a news photographer for a ride to the police station. John was convicted of first-degree murder after an insanity defense, and Jeffrey was convicted of two counts of second-degree murder. John received a life sentence; Jeffrey was sentenced to 56 to 126 years.
